Hello,
I have a discovered a similar bug in the menu: If you reserve a higher number of symbol space for the left side (the number you can choose in the configuration dialogue) than the number of entries you have activated (like videos, recent dosuments etc.) on the right side of the menu, you got a display bug if you highlight the entry above the "energy save" button: The frame around the entry is missing the lower border and lower parts of the side border.
